- This entry is not representative of the whole lake but rather, this one data source as many of the surveys were conducted in portions of the lake so the actual total count number may be higher. Lake Winnipegosis is west of Lake Winnipeg and north of Lake Manitoba. It is the third largest lake in Manitoba by surface area. It has North America's only known inland saline shoreline. See individual entries for more details. This entry compiles individual entries for Lake Winnipegosis into one total entry for indexing purposes.
